MIGHTEE H I observations of low surface brightness and ultra-diffuse galaxies in the XMM-LSS field
Astronomy & AstrophysicsUntargeted neutral hydrogen (H I) surveys are well suited to identifying low surface brightness galaxies (LSBGs) that are gas rich, and they offer a complementary view to optically selected populations.

The star formation histories of Low Surface Brightness galaxies [PDF]
International Astronomical Union Colloquium, 1999 AbstractNear-infrared images of a sample of red, blue and giant low surface brightness disk galaxies (LSBGs) were combined with optical data with the aim of constraining their star formation histories. Most LSBGs have strong colour gradients consistent with mean stellar age gradients.

A Context‐Aware Decision Support Framework for Scientific Experiment Configuration
Software: Practice and Experience, EarlyView.ABSTRACT Introduction Defining an experimental configuration is a complex decision problem for early‐stage researchers, who must map goals, constraints, and requirements onto datasets, algorithms, and parameter settings that directly affect experimental outcomes.

The σ_c-V_circ correlation in high and low surface brightness galaxies [PDF]
, 2004 We investigate the relation between the central velocity dispersion, σ_c, and the circular velocity, V_circ, in galaxies. In addition to previously obtained data, we consider an observationally homogeneous sample of 52 high surface brightness and 11 low ...

The Molecular ISM in Low Surface Brightness Disk Galaxies [PDF]
, 1999 We present models for the interstellar medium in disk galaxies. In particular, we investigate whether the ISM in low surface brightness galaxies can support a significant fraction of molecular gas given their low metallicity and surface density.

The Properties of an Edge-On Low Surface Brightness Galaxies Sample
UniverseWe analyzed the properties of a sample of edge-on low-surface brightness galaxies, which are referred to as Cao23 ELSBGs. Cao23 ELSBGs exhibit a wide range of luminosities (−22 < Mr < −13) with a mean scale length of 3.19 ± 1.48 kpc.

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, EarlyView.ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Cosmological implications of low surface brightness galaxies. [PDF]
, 1994 This dissertation briefly presents the results of a survey for galaxies that have been overlooked by previous surveys because their surface brightness, or brightness per unit area on the night sky, is too low.
